[R] problem with read.table

[Vincent MUTEAUD]

Hello R-users,
I apologize for my question but I'm a newbie. I want to read a file which 
columns separator is "\t". At the end of each row there is a "\n" to go to 
the following line. The three first lines are remarks lines and the fourth 
contains columns titles ( variables names, ids, dates, calculated values, 
observed values...) . I do:
read.table("myFile", header=TRUE, sep = "\t", skip = 3)

I obtain a strange result, lines are in a bad order:

The "\n" is read like a word and not like a symbol to skip a line.
What should I do?

Thanks
